Crataegus mollis aka Arnold Hawthorn
Taxonomy
Crataegus mollis, commonly known as downy hawthorn or red hawthorn, is a species of plant native to Eastern and Central North America. The tree can be found from southeastern North Dakota east to Nova Scotia and southwest to Texas, and prefers wooded bottomlands, prairie border, and the midwestern savanna understorey. It grows to 10–13 m high with a dense crown of thorny branches, ash-grey trunk, and 5–10 cm long leaves, though it tends to lose its foliage in summer due to leaf diseases. It blooms in spring, with white flowers that bear red and edible fruits. These ripen in late summer and fall off soon after. They require two to three years to germinate, and the seeds don’t often become available in the wild. Although uncommon in cultivation, Downy Hawthorn is a super rare houseplant that is not difficult to grow and needs regular watering to thrive. It does well with indirect light and should be within 1 foot of a window, as well as well-draining soil and occasional repotting as it doubles in size. In addition, Gypsy moths, leaf rusts and fireblight affect this species, and the thorns can be hazardous.

Difficulty
Arnold Hawthorn requires a bit more attention and knowledge to thrive, making it a suitable plant for those with some gardening experience.
Water
Arnold Hawthorn should be watered regularly, allowing the soil to dry out between waterings.
Soil
Arnold Hawthorn loves a well-draining soil. Perlite and vermiculite help with drainage, while coco coir adds organic matter, so a good potting soil mix will have all three. You can improve store-bought soil by adding some perlite to it.
Lighting
To ensure optimal growth, the Arnold Hawthorn prefers bright diffused light for 6-8 hours each day. Insufficient light can result in slow growth and leaf drop, so it's important to find a well-lit location for this plant. Place it near a window, within a distance of 1 meter (3 feet), to enhance its potential for thriving.
Toxicity
Ploi's records do not contain confirmed information on the toxicity of this particular plant. In the event of accidental ingestion of plant material with questionable toxicity by you, a family member, or a pet, it is always a good idea to consult a healthcare professional.
Fertilizer
The growth of Arnold Hawthorn is not rapid and it doesn't necessitate any extra fertilization. By replacing its potting soil once a year, it should receive ample nutrition. It is important to note that plants obtain their energy from the sun's rays, not from fertilizers.
Growth-pattern
New growth will sprout from the top of the plant as it grows upwards.
Region of origin
Arnold Hawthorn’s native range is Eastern and Central N. America - Ontario to Alabama, west to Oklahoma.
