I like the country cottage and fragrant mixes. For continual bloom, make several sowings from late April until July. Lavender is a must for any garden, whether you grow it just for hedging, for its scent or for its many medicinal uses. To grow varieties from seed, they can be set anytime from now until June in a coldframe or greenhouse. Sow the seeds one-quarter inch deep and keep soil moist.
Germination can take up to six weeks.
When seedlings appear, thin them to prevent overcrowding. Plant the seedlings out in their final positions next August or September. If your water garden suffered losses in the winter, now is the time to replace marginals and bog plants. Do not buy too many plants, as they grow at an alarming rate and you will soon have a tangled mess. Do not buy after midsummer, as plants will be past their best.
