- Soil Types: plant in finely prepared soil which has been watered for optimal growth
Germination Requirements: temperature must be at least 21°C, protect from frost.
Planting Distance (Seed Tray): sow 2-3 seeds 1cm deep 2cm apart. Label your seeds, noting planting date and variety/species.
Planting Distance (Ground): sow 2-3 seeds 1cm deep 5-8cm apart. Ensure rows are 15-30cm apart.

- F1 Hybrids: hybrid seeds are produced from two specially selected varieties that are kept in isolation. As they are produced from only two plants, seeds are almost identical genetically.
- Open Pollinated: open pollinated plants aren't isolated from other varieties, so are more genetically diverse.
- Heirloom: heirloom seeds are historic, some going back to Victorian times, others more recent. Heirloom varieties can be good or bad, depending on how careful the breeder is to maintain genetic similarity.
As hybrids are produced from two specially selected varieties, the quality is more consistent, with a higher germination rate and improved cropping. But, as they require time, resources and know-how to create, they come to the market at a higher cost. They are also genetically unstable, and so if you keep the seeds from the resultant crop, performance is usually poor. Open Pollinated seeds are highly diverse and have often been grown for successfully for decades. Seeds from the resultant crop are usually perform well.Annual, Biennial and Perennial
Annual plants complete their life cycle within a year, biennials in two years (usually only flowering in the second year) and perennials can live on indefinitely.Hardy, Half-Hardy and Tender
Hardy and half-hardy plants can survive a light frost, but the latter are best moved indoors during periods of bad weather. Tender plants must be kept indoors, until after the last frost.

Our perennials and alpines are lovingly grown by our trusted nursery, based in England. Once ready, each flourishing plant will be dispatched directly to your home.
Sustainability is one of our priorities, and as such, our perennials and alpines are delivered in environmentally friendly packaging. Aside from being recyclable, they will additionally keep them nice and secure on their journey.
- Watering: During your perennial or alpine's first growing season, you should provide them with frequent waterings. Try to also avoid wetting the foliage to reduce the risk of disease.
- Deadheading: To promote a long flowering period, you should deadhead any flowers that appear spent. Simply rescind each flower at their base, taking care to not cut other parts of the plant.
- Dividing: To really flourish, your perennials can be divided every three to four years. They can be divided when they begin to show less flowers, or appear less healthy in the middle. Make sure to only do so when they aren't currently flowering.
