Welcome to NGA, Vickygalindo83. Your plant is doing just fine.

Lenticels are brown, black or reddish pores that hydrangea stems sometimes have.

The stems themselves can have different colors (green like in yours, brown like in yours, reddish like Hydrangea Lady In Red, purplish or blackish like Hydrangea Nigra) and these can vary due to environmental conditions.

In autumn, when the plant begins to harden off for winter, green areas of the stems turn grayish, sandy, brownish colors.

Older portions sometimes remain brownish always but new stems sections start green. Then the green stays until autumn and returns in Spring, until this green part becomes "old" and remains brown from a certain point going forward.

Maintain 2-4" of mulch as food and protection from the coming summer heat and winter cold. Fertilize if it is young specimen. It appears to be small enough not to need to be pruned. I never prune any of mine unless it is to remove dead wood that does not leaf out by mid to late May. Amend the soil now if your soil is alkaline. Water when a finger inserted into the soil to a depth of 2-4" (2" for a new/young plant; 4" for an older plant) feels dry. Do not water the leaves ever, only the soil. You can begin watering 1 gallon in Spring. As temperatures typically stay above 85F (this happens in May for me), increase the amt of water (try using 1.5 gallons) and use the finger method more often to see if you need to tweak more often. As temperatures moderate in autumn, reduce waterings back to 1 gallon. Once the plant goes dormant, water it once a week or twice a week, based on local rains. Stop watering completely if your soil freezes but, restart after it thaws or when you see leaf out in Spring. Use more than 1g in Spring once the plant gets taller/wider but continue using the finger method in order not to over-water and cause root rot. Water from the center crown, where all stems originate from, outwards in all directions.

During the first two summers, the leaves will be very sensitive to heat stress (temperatures above 85F) so on hot days or on windy days, expect to see the leaves wilting. This happens because their root system is not yet large enough so they loose moisture through the leaves faster than the roots can absorb more water. As long as the soil remains moist, they will perk up all on their own by the next morning. Should you see them wilted in the morning (say, 6am), then give them water right away. Should you observe an extreme wilting episode, water immediately.

Flower buds are now "invisible" and hidden inside the stems. When they open, you will see small broccoli heads popping up. This plant appears to be a hydrangea macrophylla. Its blooms may be mophead or lacecap style. If they are colored blooms (not white), the shade of color is a function of the minerals in your potting soil. This shade of color will then change as the roots grow more outwards from the potting soil and mix with your garden soil.

Does that help? Stay safe out there, Luis
