Sweet Pea 'Blue Shift'
According to well-known sweet pea breeder Dr Keith Hammett, 'Blue Shift' is the bluest sweet pea available. He describes this variety as morphing from pink/mauve to shades of brilliant blues and aquamarines as the flowers age. From our trials, we found that the pink represents in varied shades and intensities, as do the blues, which actually brings outstanding depth to the floral display throughout late spring and early summer.
Sweet Peas prefers a sunny open position in the garden in a soil enriched with aged compost and decomposed manure. Ideally, soils should have a pH around 7 or above for optimal growth as they dislike acidic soils. Sweet Peas attach readily to any open structure that they can get their tendrils around, from simple wire fencing, to cane tepees and elaborate arbours and lattice work. It is important to set up any support before sowing or transplanting so as to avoid damaging the young seedlings as they establish. Sow seed either insitu, or in trays for transplanting. Direct sowing works very well for spring and summer sowings, while indoor sowing is best in autumn. Protect young seedlings from snails, especially during the cooler months. As they begin to flower, it is important to water regularly during dry periods and pick the flowers to prolong flowering. Note: Sweet Peas are not edible. All parts are poisonous if consumed.
