Shrub or small tree.
10-20' high and 7-15' wide.
White on top, five petals, fragrant.
In mild winter regions, possibly all year.
All lemon cultivars self-pollinate.
Years before fruiting:
3. Discard any small fruits started in the
first three years so plant can put more energy into growth.
Depends on cultivar. Oval, some cultivars
with pointed ends. Green skin turning to yellow, acidic yellow flesh.
Seedless or with seeds. Aromatic rind. Entire fruit edible
Months for fruit to ripen:
6-9. Ripe when skin is entirely yellow.
Will not ripen further after being picked, so do not pick early.
Do not allow fruit to remain on tree more than two weeks when ripe,
or fruit will become dry and tasteless.
Storage after harvest:
Lemons last about a week at room
temperature and four weeks sealed in a plastic bag in the refrigerator.
Glossy dark green, broadly lance-shaped.
Twigs may have sharp thorns.
Usually grafted onto a hardier rootstock.
Cultivars of Note:
'Eureka' blooms fall and spring and bears
year-round, has few seeds, slightly less cold-hardy and less thorny,
less resistant to insect infestation and neglect, shorter lived
'Pink Variegated Eureka' has green and
yellow striped fruit ripening to all yellow, pink flesh, blooms and
fruits nearly year-round, has few seeds, variegated leaves, less
vigorous than typical 'Eureka'.
'Lisbon' thorny, blooms in spring, bears most
of year, oblong fruit with prominent nipple, vigorous and productive,
widely grown commercially.
'Improved Meyer' is a cross between the true lemon
and either mandarin or orange, withstands a wider range of heat and cold,
has a different taste – sweeter and less acidic, thin rind has
little lemon oil flavor, making grated rind useless in recipes,
bears year-round, many seeds.
Toxic / Danger:
Not to humans. Toxic to pets.
