'Cold Steel'. Five to six well spaced frilly Spencer flowers per stem. This is a step closer to a bicoloured Sweet Pea with blue standard petals and white wings. Summer flowering, sow June-September.

15 seeds per packet.

Dorothy Eckford  

'Dorothy Eckford' a true grandiflora cultivar bred by Henry Eckford and introduced in 1903. A pure white with slightly hooded standard petals and clamped keel. The seed coats are pale and should not be soaked before sowing. Summer flowering, sow May - September.

15 seeds per packet.

Future Shock

Future Shock  

SOLD OUT 'Future Shock' Strictly Lathyrus x hammettii. An extreme morpher, think of 'Blue Vein' on steroids. A mixture of segregating lines with a pink or orange ground colour. Blue veins quickly develop, in some cases flowers becoming very dark with age. Poor seed producer so unlikely to be made available in bulk. A good opportunity for an enthusiast to select their own strain. Summer flowering. 15 seeds per packet.

'Mrs Collier' is an ancestral cultivar of historic significance - first introduced in the UK in 1905. It has primrose coloured buds which open cream, and a delicate vanilla scent. More recently it became notable as the foundation cultivar used in the cross between Lathyrus odoratus and L. belinensis, which has led to the various Lathyrus x hammettii hybrids. 15 seeds per packet.

NZ Gardener

NZ Gardener  

'NZ Gardener' was named to celebrate 75 years of publication of the NZ Gardener magazine. True blue is a rare colour in flowers and this is a step closer for Sweet Peas. It resulted from the cross 'Big Blue' x 'Blue Wonder'. It has 5-7 flowers per stem, each with clamped keels and slightly hooded standard petals.

15 seeds per packet.

Paradigm

Paradigm  

'Paradigm' like 'Paradox' has changed its tendrils back into leaves but has mid blue coloured blooms. Good as ground cover or in hanging baskets. It can also be trained as cordons on short canes, not necessarily as a teepee. It does not grow taller than 1 metre. 

15 seeds per packet.

WINTER FLOWERING SWEET PEAS

Although the original, wild Sweet Pea, Lathyrus odoratus, from which all Sweet Peas have been derived was summer flowering, strains have been developed that are able to flower at different times of the year. This is controlled by the length of daylight hours, which varies both by season and geographic location. As a rule of thumb, Summer Flowering strains require 12 hours daylight to initiate flowering, Spring Flowering strains require 11 hours, while Winter Flowering strains require only 10 hours.

SPRING & SUMMER FLOWERING SWEET PEAS

Spring Flowering types are best sown in the autumn while Summer Flowering types are best sown from mid winter in areas with mild winters like those experienced in Northern New Zealand. Spring and Summer types produce more sturdy plants, which produce strong basal shoots that soon take over from the primary shoot. Notwithstanding both the Winter and Spring strains perform very well if sown at the same time as the Summer types.

Scented SWEET PEAS

Scent is a difficult characteristic to breed. Expression of scent is very much dependant on temperature and humidity, while different people have differing ability to detect scent. Notwithstanding, Keith's work in combining the colours of the ancestral cultivars with bigger flowers and longer stems has also resulted in strongly perfumed cultivars. His 'High Scent' is recognised as the world benchmark for scent. This has smaller flowers with a clamped keel, but new introduction 'High Society' combines a waved, crisp white ground picotee edged pink flower with strong scent.

NO SOAKING REQUIRED

Very frequently, home gardeners are advised to soak seed overnight before sowing. This is unnecessary and potentially harmful for any hand harvested seed obtained from this website. Because of harvesting methods, seed from field production can on occasion result in hard seed coats, which delays or prevents germination. This is why the idea that seed needs to be soaked to identify hard seed has arisen.
