Market flowers, week after week

Fresh stems every week of the season.

Choose your flowers and a weekly stem goal. We build a dated sowing schedule from your frost dates, show where harvests overlap or run thin, and count the plants you need.

How succession works

Small sowings, often.

One big sowing gives one big flush, then nothing. Smaller sowings a week or two apart keep buckets full all season.

Quick, one-cut crops

Single-stem sunflowers give one stem and are done. Sow them every 1–2 weeks for a steady supply.

Cut-and-come-again

Zinnias, cosmos and snapdragons rebloom for weeks when you keep cutting. Two or three sowings cover most of summer.

Perennial anchors

Established lavender blooms each June to August with no sowing at all. It adds scent and structure to every bouquet.

Cut flower questions

How is the number of plants worked out?

Your weekly goal is shared evenly across your flowers. For each flower we divide its share by how many stems one plant gives per week of harvest, and allow for successions that overlap. It is an estimate, so round up when you order seed.

When does the last sowing happen?

For frost-tender flowers, the last sowing is the one that still gets about two weeks of cutting before your first fall frost. Hardier flowers can keep going a little past a light frost. Cool-season flowers like sweet peas and larkspur stop once summer heat arrives.

Why are some flowers only sown once or twice?

Dahlias grow from tubers and bloom until frost from one planting. Lisianthus and statice are slow and bloom for a long time. Extra sowings rarely pay off for them.

Do I need to sow lavender?

No. Lavender is a perennial. Plant it once and it blooms every summer from its second year. English lavender blooms first; lavandin follows in mid to late summer.

Where do the frost dates come from?

From NOAA’s 1991–2020 climate normals for the nearest weather station. If that data cannot be reached, we fall back to a rough estimate for your USDA zone, and say so.

Add lavender to your bouquet beds.

Plant once, cut every summer. Browse lavender for cutting and drying, or ask our grower assistant which cultivars have the longest stems.
