Lobularia maritima 'Easter Bonnet'
‘Easter Bonnet’ is a compact, early‑flowering series of sweet alyssum available in white, pink, lavender, and reddish‑purple selections. Plants are uniform and tidy, which suits edging and small containers. Fragrance is honey‑like and noticeable in cool weather. Bloom begins early and can continue with light shearing after peak flush. Color choice within the series lets gardeners coordinate with spring bulbs and low annuals.

How it differs

- Compact, uniform habit across multiple colors.
- Quick to establish for spring displays and cool coastal summers.

- Neat habit that stays tidy longer into the season.

- Broad color range within one series.
Care in one minute
- Choose full sun in cool‑summer areas or light afternoon shade in hot regions.
- Plant in well‑drained soil that is average in fertility and neutral to slightly alkaline (6.0 to 8.0).
- Water regularly during establishment and in prolonged dry spells; allow the surface to dry between waterings.
- Feed lightly at planting; too much nitrogen reduces bloom.
- Shear or deadhead after the first flush to prompt rebloom and keep plants compact.
- Treat as annual in most of North America; remove before winter or allow limited self‑seeding.
Watch‑outs
- Flowering can stall in high heat; cut back and water to encourage rebloom.
- Seedlings are susceptible to damping‑off in overly wet media.
- Can self‑sow; remove spent plants if reseeding is not desired.
