About Catchfly Flower Seeds
Catchfly Flower Seeds grow in full sun, partial shade positions. Expect 16 inches or 6 to 10 inches at maturity. Flowering runs summer. Harvest begins around 60 to 90 days from sowing. The figures below are the ones on the packets in this group; each product page carries the exact numbers for that variety.
When to plant
Plant in spring. Sow directly where the plants are to grow; this variety does not transplant happily. Hardy in zones 5 to 12 — your local frost dates decide the exact week.
Where to plant
Choose a site in full sun, partial shade. Water needs are average once the plants are established. Free-draining soil matters more than rich soil; seed sown into ground that stays wet rots before it germinates. Allow 8 to 10 inches between plants so air can move between them. Plan for 16 inches or 6 to 10 inches of growth when you place them in a bed or border.
How to plant
Sow 1/4 inch deep, spaced 8 to 10 inches apart. Water gently to settle the soil, then keep the surface evenly moist until seedlings or shoots appear.
How to care
Keep watering average, at the base of the plant rather than over the leaves. Grown as an annual, so plan to sow again next season. Flowers appear summer; cutting or deadheading regularly keeps more coming. Expect to start harvesting around 60 to 90 days after sowing.
