How to Grow Erigeron Profusion from Seed in South Africa
Grow a soft cloud of tiny white and pink daisies in a sunny border or patio pot. This guide helps you start Erigeron Profusion from seed, settle young plants into the garden and keep their spreading growth tidy through South Africa’s changing seasons.
The most useful starting points are gentle surface watering, good drainage and enough room for the mature mound. Choose a managed garden space: Mexican daisy can self-seed beyond where it is planted.
Erigeron Profusion: a low, spreading daisy
View Erigeron Profusion Seeds and choose a pack size. The two pack options contain 100 or 1,000 raw seeds. Raw describes the seed’s form; it does not confirm chemical-treatment status.
Profusion is Erigeron karvinskianus, also called Mexican daisy or Mexican fleabane. It forms a loose mat of fine stems and small leaves, with yellow-centred flowers that open white and age pink. It is a perennial, although local supplier Gro-Pak describes it as short-lived in warm areas. This guide is for Profusion, rather than taller cut-flower erigerons.
Quick Grow Facts
Raw seed. Surface sow and press gently into moist seed-starting mix; leave uncovered for light.
Aim for 15–18°C in the medium. Allow 14–30 days for home planning; controlled production can be quicker.
Full sun and freely draining soil. Some light shade is tolerated; avoid a wet crown or permanently soggy pot.
Usually about 15–30 cm tall, spreading 0.5–1 m over time. Local supplier guidance gives approximately 90 cm spread.
About 30 cm apart for a joining edge; allow 60–90 cm for more separate mounds and trim as they expand.
Low and spreading; normally self-supporting. First-year flowering is possible. Expect summer colour, with the season influenced by cold, moisture and sowing time.
Sow where you can keep the surface gently moist
Give Profusion seed light: Benary’s Profusion growing guide recommends germinating uncovered seed at 15–18°C. Sow on the surface and press gently for contact with the moist mix; do not bury the seed. The steps below use this method.
- Use clean trays or small pots with drainage holes and fresh, fine seed-starting mix. Moisten the mix first and let excess water drain.
- Scatter the tiny seed thinly across the surface and press it into contact with the mix. Do not bury it or add an opaque covering. No soaking, scarification or cold treatment is specified in the cited Profusion method.
- Keep the medium near 15–18°C in a bright, sheltered place, away from baking direct sun. Check the medium temperature rather than relying only on the room forecast.
- Water with a fine mist or briefly from below so seed is not washed away. Keep the surface evenly moist through emergence, without leaving the tray standing in water. If using a clear lid, ventilate it and remove it as seedlings emerge.
- Be patient. Gro-Pak gives 14–30 days; Benary reports about seven days under controlled conditions. These are different growing contexts, not a promise that every tray will emerge within one week.
Trays make these small seeds easier to manage. Sowing into a final container is also supported by the cultivar guide; keep the surface sheltered and thin crowded seedlings. Open-ground sowing is harder to control because rain, wind and drying can move or kill exposed seed. Do not broadcast seed into natural areas.
Move sturdy seedlings and plan for their spread
Pot on crowded seedlings when they have true leaves and are large enough to handle without crushing the stems. Hold a leaf rather than the stem, keep the roots supported and move the plant with a small plug of mix. There is no fixed transplant day: wait for a sturdy plant and a rootball that holds together.
Gradually introduce young plants to outdoor light and wind over about a week, extending this if conditions are harsh. Keep them protected from frost. Plant at the same depth as in the pot, firm gently and water the rootball thoroughly; do not bury the crown.
The supplier’s 30 cm spacing creates a joining edge, rather than limiting each plant to 30 cm wide. For distinct mounds, a practical starting distance is 60–90 cm, based on their eventual spread, with trimming where growth meets. Use the wider end in humid sites. In containers, leave room for trailing stems and avoid crowding the crown with other vigorous plants.
Profusion is suited to edging, rock gardens and containers. It normally needs neither staking nor compulsory seedling pinching. Intensive spacing and support systems for tall cut flowers are not needed for this low, spreading plant.
Choose a sowing window for your region
Spring and autumn are useful starting seasons, not a single national calendar. The following are practical climate adaptations: use the sowing temperature above, your local frost risk and the condition of the soil to choose the week.
Winter-rainfall Western Cape
Spring establishment avoids leaving tiny plants in prolonged cold, saturated soil. Protect trays from heavy winter rain and choose a draining bed or pot. Autumn sowing is an option in mild, sheltered sites when plants have time to establish. Water young plants through the dry season.
Frost-prone interior
Start under protection if needed and plant outside after local frost risk has eased. Harden off gradually. Avoid severe cutting back immediately before frost; wait for spring growth. Established winter survival depends on exposure and drainage, so do not assume a cold-rating guarantee.
Humid coast and KZN Midlands
Use airy spacing, drainage and gentle soil-level watering. Avoid keeping trays or crowns constantly wet during humid weather. Midlands sites can still frost, so check your altitude and local conditions. Watch for self-sown seedlings beyond the planting area.
Hot-dry and subtropical interior
Choose a cooler spring or autumn window when you can maintain the germination temperature. Shelter trays from drying wind and hot afternoon sun. Gradually increase light before planting out and water young rootballs reliably. Established drought tolerance does not protect exposed seed or new seedlings.
Keep the mound flowering and tidy
Water new plants whenever their rootballs begin to dry. Established plants tolerate dry spells, but prolonged drought can reduce the flowering display. Check pots regularly and water thoroughly when needed, allowing excess water to escape. Poor drainage cannot be corrected simply by feeding more.
Avoid heavy nitrogen feeding, which encourages soft growth. Garden plants in reasonable soil need little extra feeding; container plants may need a modest balanced feed once the potting mix’s initial nutrients are used. Follow the fertiliser label and feed during active growth. Keep air moving through the planting and remove dead or damaged material.
Trim straggly stems when they obstruct paths or lose shape. In spring, once healthy new shoots appear and severe frost risk eases, cut older woody growth back towards those shoots. Routine deadheading is not essential for continued flowers, but removing developing seedheads helps reduce unwanted seedlings. A container does not stop airborne seed escaping.
Profusion can flower in its first year without a winter chilling treatment. Benary’s 12-week spring crop schedule is a commercial reference from Central European trials, not a South African seed-to-flower deadline. Sowing season, plant size, weather and care affect the display; this is a flowering ornamental rather than a food crop.

Troubleshooting: no seedlings, weak plants or few flowers?
- No seedlings after a week
- Keep checking surface moisture and temperature; the local supplier’s planning window is 14–30 days. Do not assume failure from the breeder’s faster production figure.
- Poor or patchy germination
- Check whether seed was buried, washed away, allowed to dry or exposed to heat or cold outside the target range. Start a small fresh tray with surface-sown seed and steadier conditions. If nothing emerges after the expected window, retain the packet details when asking for help; seed condition cannot be diagnosed from timing alone.
- Seedlings collapse at soil level
- A soft, narrowed stem can indicate damping-off. Remove affected seedlings, avoid shared standing water and start any replacement sowing in clean trays with fresh mix. Improve light and ventilation without drying the seed surface. University of Minnesota Extension explains seedling damping-off.
- Plants wilt after transplanting
- Check the rootball itself: it may be dry even when surrounding soil looks damp. Water appropriately, shelter briefly from harsh wind or sun, and allow gradual acclimatisation. If the soil is already soggy, improve drainage rather than adding more water.
- Weak, stretched growth or few flowers
- Review light, crowding and excess nitrogen. Move containers to a brighter suitable spot and reduce unnecessary feeding. Prolonged drought can also limit the display.
- Wet, declining crowns or damaged leaves
- Check for trapped water and remove dead material. Inspect both leaf surfaces before assuming a pest is responsible. Profusion is not immune to problems: identify the cause before using any treatment, and use only a product registered for that use according to its label.
- Seedlings appear outside the bed
- Remove them promptly and trim developing seedheads. Keep checking nearby paving and soil; do not allow the plant to move into natural vegetation.
Grow responsibly and keep seed for sowing
SANBI records Erigeron karvinskianus as a naturalised exotic in South Africa. Keep it in managed garden beds or containers, remove unwanted seedlings and do not scatter seed in veld, waterways or natural areas. Near sensitive habitat, ask your local conservation authority about suitable planting choices.
Grow Profusion for ornamental flowers, not for eating. Do not eat seed sold for sowing or use it for sprouts. Raw seed is not proof of untreated or food-grade status; follow any handling and treatment instructions on the physical packet. Keep sowing seed out of reach and prevent children and animals from eating the plant.
