J did not formally propose marriage to Hester until the end of the summer. For the first months he could think of nothing but clearing the debts caused by the crash of the tulip market. The Tradescants, father and son, had invested the family fortune in buying rare tulip bulbs, certain that the market was on the rise. But by the time the tulips had flowered and spawned more bulbs under their perfect soil in their porcelain pots the market had crashed. J and his father were left with nearly a thousand pounds owed to their shareholders, and bound by their sense of honour to repay. By selling the new Virginia plants at a handsome profit and by ensuring that everyone knew of his new maidenhair fern, an exquisite variety which everyone desired on sight, J doubled and re-doubled the business for the nursery garden, and started to drag the family back into profit.

The maidenhair fern was not the only booty that visitors to the garden sought. John offered them new jasmine, the like of which no-one had ever seen before, which would climb and twist itself round a pole as rampant as a honeysuckle, smelling as sweet, but flowering in a bright primrose yellow. A new columbine, an American columbine, and best of all of the surviviving saplings: a plane tree, an American plane tree, which John thought might grow as big as an oak in the temperate climate of England. He had no more than half a dozen of each, he would sell nothing. He took orders with cash deposits and promised to deliver seedlings as soon as they were propagated. The American maple which he brought back with such care did not thrive in the Lambeth garden though John hung over it like a new mother; and he lost also the only specimen he had of a tulip tree, and nearly came to blows with his father’s friend the famous plantsman, John Parkinson, when he tried to describe the glory of the tree growing in the American wood, which was nothing but a drying stick in the garden in Lambeth.

‘I tell you it is as big as an oak with great greasy green leaves and a flower as big as your head!’ John swore.

‘Aye,’ Parkinson retorted. ‘The fish that get away are always the biggest.’

Alexander Norman, John’s brother-in-law and an executor of John Tradescant’s will, took over some of the Tradescant debts on easy terms as a favour to the young family. ‘For Frances’s dowry,’ he said. ‘She’s such a pretty maid.’
